could the shaft be showing a reflected temperature from a nearby object?
Have you stopped the motor and verified the shavt temp with a contact thermometer?

Be careful when you measure with a non contact thermometer. Paste a non conductive tape, usually black color, on the shaft. On the other side, this high temp is obviously affecting the bearings; whatever you do, keep in mind bearings change.
It could be the infrared radiation of temp of the bearings better shown on the shaft than on the cover.
